Multiple panes

6 Jun 20238 minutes to read

Chart area can be divided into multiple panes using the rowDefinitions and columnDefinitions properties.

Row Definitions

To split the chart area vertically into a number of rows, use rowDefinitions of the chart.

• You can allocate space for each row by using the unit option that determines whether the chart area should be split by percentage or pixels for the given rowHeight value of the rowDefinitions.

• To associate a vertical axis to a row, specify the rowDefinitions index value to the rowIndex property of the chart axis.

• To customize each row’s horizontal line, use lineColor and lineWidth property.

JAVASCRIPT

"use strict";
var rowDefinitions=[{
            //  Split first row of the chart area
            unit : 'percentage',                 
            lineColor : 'Gray',
            rowHeight : 50,
            linewidth : 0
            }, {
            //  Split second row of the chart area
            unit : 'percentage',                 
            lineColor : 'green',
            rowHeight : 50,
            linewidth : 0
}]

var axes=[{
            //Create secondary axis and bind it to second row of chart area
            name: "yAxis1",
            rowIndex: 1
}]

var series=[{
            //Binding vertical axis name
            yAxisName: "yAxis1",
            // ...
}]

ReactDOM.render(
    <EJ.Chart id="default_chart_sample_0"
	rowDefinitions={rowDefinitions}
	axes={axes}
	series={series}
    >        
            
    </EJ.Chart>,
		  document.getElementById('chart')
);

Row Span

For spanning the vertical axis along multiple panes vertically, you can use rowSpan property of axis.

JAVASCRIPT

"use strict";
var rowDefinitions=[{

                         // ...
                  },{

                         // ...
}]

var axes=[{

                          // ...
}]
		
var primaryYAxis={
                    //  Span the PrimaryYAxis                    
                    rowSpan : 2,
}

var series=[{
		// ...
}]

ReactDOM.render(
    <EJ.Chart id="default_chart_sample_0"
	rowDefinitions={rowDefinitions}
	axes={axes}
	series={series}
    primaryYAxis={primaryYAxis}
    >        
            
    </EJ.Chart>,
		  document.getElementById('chart')
);

Column Definitions

To split the chart area horizontally into a number of columns, use columnDefinitions of the chart.

• You can allocate space for each column by using the unit option that determines whether the chart area should be split by percentage or pixels for the given columnWidth value of the columnDefinitions.

• To associate a horizontal axis to a column, specify the columnDefinitions index value to the columnIndex property of the chart axis.

JAVASCRIPT

"use strict";
var columnDefinitions= [{
                //  Split first column of the chart area
                    unit : 'percentage', 
                    columnWidth : 50,
                }, {
                    //  Split second column of the chart area
                    unit : 'percentage',                 
                    columnWidth : 50,
                }]		

var axes=[{
			//Create secondary axis and bind it to second column of chart area 
            name: "xAxis1",
            columnIndex: 1
            // ...
        }]
		
var series=[{
            //Binding horizontal axis name
            xAxisName: "xAxis1",
            // ...
}]

ReactDOM.render(
    <EJ.Chart id="default_chart_sample_0"
	columnDefinitions={columnDefinitions}
	axes={axes}
	series={series}
    >        
            
    </EJ.Chart>,
		  document.getElementById('chart')
);

Column Span

For spanning the horizontal axis along multiple panes horizontally, you can use columnSpan property of axis.

JAVASCRIPT

"use strict";
var columnDefinitions= [{
                      // ...
                  },{
                      // ...
}]	

var axes=[{
              // ...
         }]
		
var series=[{
              // ...
           }]
		   
var primaryXAxis= {
              //  Span the PrimaryXAxis                    
              columnSpan : 2,
}

ReactDOM.render(
    <EJ.Chart id="default_chart_sample_0"
    primaryXAxis={primaryXAxis}
	columnDefinitions={columnDefinitions}
	axes={axes}
	series={series}
    >        
            
    </EJ.Chart>,
		  document.getElementById('chart')
);
